 Here's a simple code example to get you started. In order to create any object from pyLast, you need a Network object which represents a social music network that is Last.fm or any other API-compatible one. You can obtain a pre-configured one for Last.fm and use it as follows:
 
-```

 import pylast
 
 # You have to have your own unique two values for API_KEY and API_SECRET

 export PYLAST_USERNAME=TODO_ENTER_YOURS_HERE
